ABSTRACT:
A fuel injection nozzle for internal combustion engines is proposed, which includes a valve needle stressed by a closing spring and a damping device to partially damp the opening movement of the valve needle. The damping is effected in accordance with the stroke frequency, the stroke length of the valve needle, or both, or the quantity of fuel throughput per injection cycle, and the damping effect is preferably variable automatically by shifting the time of the onset of damping relative to the onset of injection. As a result, an adaptation of the damping effect to the operating state of the engine at a particular time can be attained which substantially meets the ideal parameters for such damping.
